It doesn’t rain, it pours. Not only have a number of jailbreak solutions appeared for PS3 over the past few weeks, but the devices being used to perform the jailbreak are also expanding.

The jailbreak carried out in the video above has to be the most novel and funniest yet. It uses a flash application called PS3JB on a Texas Instruments TI-84 Plus calculator to run the PSGroove exploit.

The calculator is connected to the PS3 via a USB port and the PS3JB application run. Then the PS3 is powered on, the app does it’s thing, and the PS3 is ready for unsigned code.

As PSGroove is open source it shouldn’t be surprising that hackers are experimenting with it, and it’s got to give you a buzz to jailbreak a friends PS3 using a graphing calculator with a 15MHz processor.

Unfortunately, Sony has blocked jailbreaking with the release of firmware 3.42 for the PS3 this week. So enjoy calculator jailbreaks while you can, as the next new game you buy, or the next time you access PSN and get the update, they won’t work any more.
